Application filed April 17, 1916. Serial No. 91,617.

1 '0 all whom it concern:

Be itknowntha't I, HonATIo G. GILLMon, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented new and useful Improvements in Anticreepers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invent-ion relates to improvements in anticrecpers, anchors or stays for railroad rails.

The chief object of my invention is to provide a light, simple and inexpensive anticreeper which may be readily and securely applied to the rail base and which is efiec tive in resisting creeping.

Other objects are to provide an improved anticrceper constructed in one piece; to provide an anticreeper of this type having improved means for holding it to the rail base; to provide an anticrecper. which does not work loose after being applied but which may be readily removed if desired and-to provide an anticreeper which operates with the maximum of efficiency under all conditionsf In the accompanying drawings, I have illustrated a preferred form of the invention. in which: I

Figure 1 is a side view of theanticreeper showing a portion of the rail in side elevation; Fig. 2 is a rear view of the anticreeper showing the rail in section. Fig. 3 is a plan view thereof showing a portion of the rail. Fig. 4 is a front view thereof after the device has been placed upon the rail and before being locked in operative position upon the rail which is shown in section. Fig. 5 is a rear view of the anticreeper in one of the positions assumed when applying the device to the rail which is shown in section.

Similar letters refer to similar parts throughout the several views.

In Figs. 1, 2 and 3 is shown email A of the usual type, having a head B and a. base flange C. resting upon one of the usual crossties D. The anticreeper or rail anchor E extends transversely underneath the rail base and is provided at one end with an arm F, extcuding upwardly and inwardly and adapted to engage the upper surface of the rail base flange G at one side of the rail at G. The portion of this arm F extending over the base flange G is preferably beveled as at H, Fig. 2 and at the other end of the anticreeper E there are two portions I and It at opposite sides of the transverse portion of E arranged to engage the edge of the extends upwardly and inwardly from E and has surface N arranged to engage the upper surface of the rail basetlange C and surface ,0 arrangedto engage the under side of the head B of the rail. The portion Mis so formed that, in its normal coudit-iomthe angle between the surface N and the body of the anticreeper is greater than the angle of the top of the rail base flange C to the bottom the rail base as illustrated in Fig. 4e. The body portion of the anticreeper E has a portion with surface P arranged to engage the bottom of the rail when the anticreeper is in operative position (in the rail and a beveled portion Q which is out of contact with the fail bottom. At the opposite ends of the anticreeper E are two tie engaging portions R and S, strengthened by ribs T and arranged to extend forwardly at the lower portion as at U, in Fig. l. The portion I is beveled at the upper part as at V, Fig. 2, and the portion Kai's beveled at the bottom ab at WV, Fig. 4. lfhe surface X on the arm F forms a shoulder engaging the edge of the rail base. he webs Y strengthen the connections of the portions of the anticreeper one with the other.

To place the anticreeper in position upon the rail, it is placed transversely beneath the rail base and rotated through such an. angle as will bring the portion I below and .the portion K above the rail base flange C. With the anticrecper in this position the arm'F can be brought to a position beyond the edge ofthe rail base C at the side thereof opposite to that above and below which the portions I and K of the anticreeper are. This position ofthe anticrecper is illustrated in Fig. From this position illustrated in Fig. 5, the anticreeper E may be drawn transversely of the rail until the beveled portion H of the arm F engages the top of the rail base flange C, when by turning the antiereeper so that the portion M will be vertical the portions I and K will be brought into engagement with the edge of the rail base flange C at the side of the rail opposite to that engaged by the arm F. The beveled surfaces V and W of the portions I and K the rail base flange C will during this turning of the anticreeper E act with a cam action upon therail edge so that in the final position of the anticreeper E with the portion M vertical the rail will be gripped transversely between the shoulder formed bythe surface X of the arm 1" and the portions I and K. The teeth or serration L. on the portions 1 and K are provided so that if the rail should be wider than the usual or standard width, there may be some upsetting of these teeth or serrations and the deformation of the teeth thus adjust the distance between the surface X and the portions l and K of the anticreeper to the wider base flange: The anticreeper, after the movements referred to above, will oocupy the position illustrated in Fig. 4; and in this position the surface P of the transverse portion of the anticreeper E will enage the bottom of the rail base and the surface N of the vertically disposed portion M will engage the upper corner of the edge of the rail base flange (J at Z.

To effectually grip the anticreeper upon the rail and maintain it inoperative position upon the rail the vertically disposed portion M is driven in toward the rail and wedged in between the under side of thehead B and the upper surface of the base C of the rail. The anticreeper is preferably constructed of such material as malleable iron which has. a certain amount of resiliency but may also be deformed and in driving the upper portion of the portion M toward the rail, by force applied near the top,

it tends both to spring and to deform and there is exerted an upward pressure of the surface 0 of the portion M upon the under side of the rail head B and a downward pressure of the surface M upon the top of the rail base C and at the same time the anchor as a whole tends to move angularly slightly pivoting upon the upper surface of where it is engaged by the surface N of the portion M and the surface P of the transverse portion of the anticreeper E is thus pressed upwardly against the bottom of the rail base C. In the final operative position of the anticreeper, the rail is gripped transversely be tween the portions 1 and K and the surface X of the arm F and vertically between the surface G of the arm F and the surface bl of the portion M and the surface P of the anticreeper E extending transversely beneath the rail; and, at the same time, the vertically disposed portion M is driven tightly in between the rail head l3 and the rail base C. Theanticreeper is thus made to eifectually grip the rail and is efficiently locked in position upon will at all times efficiently resist any tendency of the rail to move forward in the direction of the arrow in Fig. 1. Movement of the rail in the reverse or backward dithe rail so thatit M out from the V tion K is above rail base flange C when the 5 anticreeper E may be removed from the rail.

It is obvious that various changes may be made in the structure described, without departing from the spirit of the invention. The device need not necessarily be made as a casting, but of other material than cast material. I desire therefore to cover in the appended claims whatever modified structures fall within the scope of the invention.
